It's impossible because hedge funds trade many different stock, not just Bitcoin.
You should do some research before asking a question mate.
This is why I am asking this question. I want to know if there is one specifically for bitcoin no other.
I don't want the up&down of its price to affect my investing in the long run.
I have done the research but there is no such resource because it seems that companies don't want to be involved with such risk associated with it for offering such a fund.
